Pearson Correlations between Sustained Attention Performance, Response Inhibition, and Volume Estimates Extracted from the Right Inferior Frontal Gyrus and the Posterior Portion of Right Inferior Fronto-occipital Fasciculus

		RVP-Total Hits	SSRT
r-IFG	Pearson	.267a	.002
	p value	.039	.985
r-iFoF	Pearson	−.103	.294a
	p value	.435	.023

Significant correlation between gray and white matter volume and measure of sustained attention and response inhibition.

r-IFG, right inferior frontal gyrus; r-iFoF, right inferior fronto-occipital fasciculus; RVP, rapid visual information processing test of sustained attention; SSRT, stop signal reaction time.

^aSignificant correlation (two tails).
